Anaemia by calves

Anaemia is a condition in which too little blood pigment substance (haemoglobin = Hb) is in the blood.

Definition

Anaemia is a condition in which too little blood pigment substance (haemoglobin = Hb) is present in the blood. Anaemia in which visible symptoms occur (increased hart rate during exertion and an accelerated breathing), is seen in a haemoglobin level lower than 2.5 mmol/liter (4g/100ml).
From the animal health point of view, the Hb in the blood should not be too low. 

Cause

Anaemia is a result of an inadequate formulation, a too large loss or a too big degradation of blood pigment.
Insufficient production of blood pigment can be caused by a shortage of construction materials and consumables (including iron, copper, cobalt, vitamin B12) or because the bone marrow or liver function is disturbed.
A too large loss can occur from chronic blood loss, for example, in a gut- or abomasum ulcer.
A too big degradation can be caused by an increased breakdown of red blood cells in a chronic infection caused by viruses, bacteria or parasites. 

Description

The blood- and muscle pigment ensure the transport of oxygen to and in the tissues. At a shortage of blood pigment substance (haemoglobin) have the calves a decreased appetite, stay behind in growth and have pale mucous membranes. 

Treatment

Calves with anaemia have need for a vitamin boost. Feed during 5 days a vitamin supplement, which should contain iron and enough trace elements. That is how you can get your calves fast on the right level. The providing of a mineral block can help.
